HRCQ (HRQ) Drill Rods Overview
* Material : 4130

* Tubing
• High quality alloy steel tubing
• Consistent concentricity, straightness and heat treatment
• All tubing available in DCDMA sizes

* Thread
• Tapered, course threads (3 threads per inch) provides easy make and break
• Load efficiency of 30% provides sufficient strength for average applications

* Thru-wall Heat Treatment
• Provides 140% material strength
• Heat treated box threads significantly increases thread wear life

* Case Hardening
• Significant research, development and field testing have resulted in a hardening process that is unequalled.
• Pin thread crest is hardened to nominal 55 HRC to eliminate damaging adhesion wear
• Eliminates the transfer of wear material back and forth which is what happens between threads of equal hardness, leading to large scale galling and joint seizing

Note: For making sure the performance of the drill rods, never mix our rods with any another manufacturer's rods together, also it may cause machinery failures and catastrophic accident.
